Help Exit bags - 25 cm to 38 cm. How to get bigger ones? (collecting ideas)

[LittleJem]

I've just looked at the largest oven bags online and the measurements are 25 cm by 38 cm. I guess that isn't too much air before it runs out.

I just wanted to collect ideas on larger bags that could be safely used as exit bags.

Thank you

Here is my setup:

This canister has a built-in valve that can be set to 15L/min. It costed me almost 400€ to buy this setup so quite expensive. More information about the canister: Albee Weld Argon 11L 99.99%.

This one by Oneness is quite creative by using a water tight dry bag instead of an ordinary bag. Not sure if he succeeded or not.
